Hi:
Just a point of clarification regarding the fields Album Artist and Album Artist (auto). I use Album Artist (auto) for this purpose. Whenever a solo artist (by name) has a guest appearance (i.e. featuring ... or Artist & Someone Else or Artist; Guest), I make sure during the rip (I use dBpoweramp) that I explicitly state that the Album Artist field contains just the solo Artist name (see image). This overrides the default value of (Multiple Artists) that would normally be stored if I did not make the explicit tag to the Album Artist field. With this approach I can always depend on the Album Artist (auto) field to contain the Album Artist name that was intended to be highlighted by a particular album. In normal Album Artist occurrences where just the Album Artist name appears for every track, Album Artist (auto) will default to the same value that appears in Artist and Album Artist will be blank. This is why I use Album Artist (auto) for my views.
Cheers,
Lawrence
